The Sentry 101 duress system is an affordable solution for providing rock solid state-of-the-art detection of duress (panic) alarms with optional man-down detection. In the event of an alarm, the master receiver will beep to alert staff and display the number of the pendant that is in alarm. The beeper is silenced by pressing a button on the front of the master receiver. The master receiver has a rechargeable backup battery which will operate the unit for about 8 hours in the event of a power failure. LED lamps on the front of the unit will light and flash if AC power fails or the backup battery is running low. The Sentry 101 system is completely wireless – there is no interconnect wiring to install. The master receiver and repeaters have only a small wall transformer to be plugged into a nearby outlet. As an option, the Sentry 101 can call remote telephone numbers or broadcast to local area pagers.

Pendants
The DS 1235 pendant comes with a belt clip and with single button or double button activation. The single button version is also available with an extra heavy duty case for demanding environments (DS 1235-I – “I” for Industrial). The DS 1235-S and the DS 1235-I can be ordered with man-down option. The DS 1223-S is available with the belt clip, neck lanyard or optional wrist band and is water resistant to a depth of 1 meter. The Sentry 101 system supports up to 32 pendants or transmitters. Pendants have an approximate true-line-of-site range of 1/2 mile but this will be diminished by buildings, walls, floors, trees or other obstructions. Inside buildings, range is typically hundreds of feet depending on the nature of the structure. Range is extended by installing wireless repeaters.

Man-Down
The man-down option for the DS 1233 and DS 1235 pendants will detect the tilt of the pendant beyond 60 degrees. When the pendant is so tilted, it will beep for approximately 30 seconds. If the pendant has not been righted in that time period, it will send a duress alarm. To avoid false alarms for simple activities like tying one’s shoelaces, the beeper reminds the wearer that an alarm is about to occur. The man-down option is not available for the DS 1223-S.

Remote Reporting
Alarms can be announced to telephones, pagers (both subscription and on-site systems) and hand held radios. Up to 4 telephones can receive a pre-recorded voice message. Instead of one or more voice message calls, we may substitute calling typical subscription type numeric pagers. A more powerful on-site paging system will display an alpha-numeric alarm message on any number of pagers. Hand held radios can receive a pre-recorded voice message describing the alarm.

Supervision
The Sentry 101 pendants are supervised for both low battery and operational readiness. The system will detect a low battery condition from any pendant or transmitter and report it. This will occur approximately 2 weeks prior to the end of the battery life. Batteries are commonly available and can be replaced by the user. Battery life is 1 to 2 years. Each pendant and transmitter reports to the master receiver with a check-in signal every 60 seconds. If a transmitter fails to report to the master receiver within a 4 hour window, a supervisory alarm is created. If special circumstances warrant, the check-in window can be set from 1 to 99 hours. This must be done by CISCOR prior to shipping the system.

Repeaters
As mentioned previously, the range for pendants indoors will be in the hundreds of feet depending on the composition of the building structure. If necessary, range is extended with the use of wireless repeaters. Repeaters intercept the alarm transmission and then re-transmit with 30 times more power. True-line-of-site-range for a repeater is about 2 miles. Like pendants, this range is reduced by obstructions. Multiple repeaters can be installed creating a wireless network capable of dependable alarm reporting for very large areas covering many acres or several miles. Repeaters require no wiring with only a small 110vac transformer to be plugged into the nearest outlet. Each repeater has its own backup battery power supply. They may be installed outdoors, and it should be noted that cold climates will require an optional heater package.

900 MHz Frequency Hopping Spread Spectrum
This is simply a fancy term which means it doesn’t get any more reliable than this. Spread spectrum technology was developed by the military to prevent jamming and interference to radio communications. The alarm signals are spread out over a wide radio spectrum randomly hopping from channel to channel. If there is interference from equipment, CB radios or other sources, the system can still deliver. When lives hang in the balance, we should expect nothing less.

Upgrades
All Sentry 101 pendants and wireless repeaters will function with CISCOR’s powerful server based OneSource software. This system is capable of providing the location of pendants as well as the ID of each individual pendant. Thousands of wireless devices may be incorporated.

Other Transmitters
In addition to pendants, we can report alarm conditions or change-of-state on/off status from equipment, doors, gas detectors or other devices. For example, we may want to know when pressure or temperature exceed normal boundaries. Also, wireless smoke detectors can be incorporated.
